Resize Image for Instagram (2026 Guide)

Get the exact pixel dimensions for Instagram posts, stories, and reels. Resize in your browser.

No signup. Images processed in your browser — nothing uploaded.

Instagram has specific dimension requirements for every format. Using the wrong size means cropping, black bars, or blurry uploads. fileGOD resizes images to exact Instagram dimensions for 2026: 1080x1350 for posts, 1080x1920 for stories and reels, 1080x1080 for square posts. All processing runs in your browser. Instagram compresses uploads on their end — uploading at exactly the recommended dimensions minimizes this compression and produces the sharpest result. Portrait posts at 1080x1350 (4:5 ratio) currently perform best in the algorithm, taking up more screen real estate and driving higher engagement. fileGOD makes hitting these exact specs effortless with preset dimensions and smart cropping.
